Update Opera Presto data for Element API (#7208)

This commit updates and/or corrects the Opera Presto data for the
Element API based upon results from the mdn-bcd-collector project
(using results from Opera 12.14 and 15).  Updates to Blink-based
versions of Opera is defered to the Chrome-updating PR.
